the most negative electron affinity is most likely associated with which type of atoms?\no large nonmetal…

Brief Explanations:

Electron - affinity is the energy change when an electron is added to a gaseous atom. Non - metals have a greater tendency to gain electrons compared to metals. Small non - metal atoms have a high effective nuclear charge and a small atomic radius. This allows them to attract an additional electron more strongly, releasing more energy (resulting in a more negative electron affinity). Larger atoms have more electron shielding, reducing the attraction for an added electron, and metals generally tend to lose electrons rather than gain them.

Answer:

B. small nonmetal atoms
